## Questions & Answers

**Q: Can the sliding mechanism on the (30oz) lid be disassembled for washing? My milky tea gets inside and is starting to get crusty/flaky...**
A: I have the older version of the lid too. 
It usually comes out clean if you put it through the dishwasher but needs a good shake afterwards. 
You can also try holding it sideways under warm running water for a min and then vigorously shake it over the sink. Try the other side and repeat. Do this with the lid closed and opened.

**Q: Is there a way to keep the straw from rattling around?  I use it in a quiet office and it so noisy.**
A: You can get silicone bumpers that slide onto the straw on either side of the lid, to hold the straw in place and keep it quiet. Some products even come with tips as well as bumpers, in case you don’t care for the metal straw hitting your teeth. Amazon sells them. I have had zero rattling since I started using them, and I enjoy the tips, no burning your lips on a hot straw.

**Q: Just got mine in and I love it. I can tell I’ll need more straws so what size should I get? I like the wide straight one. What size is it?**
A: I have a 40oz Beast which I love. I use the metal extra long straws, however, the regular size metal straws can work.

**Q: Can u use this cup without the straw**
A: Mine has no vent which makes it difficult to get much liquid out. I’m considering returning it as I don’t like drinking out of a straw.

    Solid, reliable and a quality made product.
  

*by D***G on Reviewed in the United Kingdom on 15 June 2018*

After putting this product through its paces over the course of the last month I feel happy to submit a review for it, this is a review of the 20oz version.First impressions were good; the tumbler is a quality, premium product that feels solid yet lightweight, the inclusion of two straws and a specialise crooked cleaning brush are exception additions also.I have used the Beast at a convention for five days during which time it contained lots of hot coffee and many different cold cocktails.It keeps its temperature incredibly well if you use the cap provided and I feel this is the best way to use the Beast.Testament to its insulating properties I went to bed at 2 am one night and when I woke at around 8 in the morning the ice cubes were still kicking about inside!Since the convention I've used the Beast to hold hot and iced coffee among other chilled drinks and so far I have had no issues with it at all.If you're looking for a new travel cup for that morning commute, or for your cupholder on a road trip or just a special something to keep your drink at it's ideal temperature where ever you are all day long then this is the one for you!

    Superb Quality Product
  

*by B***S on Reviewed in the United Kingdom on 22 May 2019*

When we first took the tumbler out the box it was easy to see this was a quality product. Everything about it feels like it was made to a very high high standard. They keep the temperature of the drink inside both hot or cold and the metal straws are perfect along with the included cleaning tool. Thank you for delivering the quality promised.Also it's environmentally friendly and who doesn't love that!

    Great but leaks sometimes
  

*by L***A on Reviewed in the United Kingdom on 28 April 2024*

This is great but have to leave the lid open for quite some time so it doesn’t leak when hot coffee in there, I closed it after 20mins so I could travel with it and it still leaked but it is solid and I still love it, just can’t close it for a good while, coffee does stay warm still though
